ISO DIS 11812

Description / Abstract: This International Standard specifies requirements for recesses and cockpits in terms of watertightness, draining time, and sills in way of cockpit companionway doors or hatches, for small craft up to 24 m length of hull. Recesses located in elevated part of the craft shall be considered by the scope of this standard. This standard only considers normal operation of craft, as defined in ISO 8666.

Unattended craft recess issues are considered out of the scope of this standard;

It does not set requirements for the size and the shape of a recess or cockpit, or where it shall be used. It only considers draining by gravity, and not by pumping or other methods.

This international standard does not guarantee that the water contained in a watertight or quick draining recess or cockpit will not harm stability and floatability, which are covered by ISO 12217.

NOTE 1 The term "quick-draining" has been chosen in differentiation from the common understanding of "selfdraining" where water may be drained overboard in certain conditions, but without specified draining speed, height of bottom or sill, etc.
